Fixing Python Pip on Windows – Command ‘Cl.Exe’ Failed Quickly


If you are a Windows user and work with Python, the chances are that you have encountered the Command ‘Cl.Exe’ failed quickly error at some point. This error can occur when trying to install packages or updating pip, leaving you unable to proceed with your project.

The Problem

The Command ‘Cl.Exe’ failed quickly error is caused by an issue with Microsoft Visual C++ 14.0 or higher. When pip tries to compile packages that include C code, it requires a C++ compiler. However, the necessary C++ components may not be present on your system, resulting in this error.

The Solution

Fortunately, there are several ways to fix this issue:

Option 1: Install Microsoft Build Tools

This is the most straightforward solution. You can download and install Microsoft Build Tools, which includes Microsoft Visual C++ Build Tools. This installation will provide you with the necessary components to compile C++ code for Python packages.

Option 2: Install the Windows SDK

If Option 1 doesn’t work, you can try installing the Windows SDK instead. This installation includes the necessary components required to compile C++ code for Python packages. You need to make sure you install the correct version of the SDK that matches your Python installation.

Option 3: Use Anaconda

If you don’t want to install Microsoft Build Tools or the Windows SDK, you can use Anaconda as an alternative. Anaconda is a package manager that includes many pre-built Python packages with their necessary dependencies, including C++ compilers. This option is the most comfortable if you don’t have much experience with installing Visual Studio or similar tools.

Comparing the Options

Here is a comparison table for the three options:

Option Pros Cons
Microsoft Build Tools Easy to install and use Can take up significant disk space
Windows SDK Includes more C++ components than Build Tools Can be tricky to select the right version of the SDK
Anaconda Comes with pre-built packages, making it easy to set up Can be slower and takes up significant disk space


The Command ‘Cl.Exe’ failed quickly error can be a frustrating problem for Windows users working with Python. However, there are several solutions that you can implement to fix it. All three options have their pros and cons, so you need to choose the best one for your needs. Once you have installed the necessary C++ components, you should be able to use pip to compile packages without encountering any errors.

Personal Opinion

From my personal experience, I find that installing Microsoft Build Tools is the easiest and quickest option to fix this error. It provides all the necessary components to work with Python packages without taking up too much disk space. However, the Windows SDK is a viable alternative if you need more components, while Anaconda is the best option if you don’t like dealing with building and installing packages manually. Whichever option you choose, it’s essential to ensure that you have everything set up correctly to avoid encountering the Command ‘Cl.Exe’ failed quickly error.
